联合检测尿β_2微球蛋白与炎性因子在合并高血压2型糖尿病患者早期肾损害的应用价值

目的探讨尿β_2微球蛋白(β_2-MG)与超敏C-反应蛋白(hs CRP)、白细胞介素-6(IL-6)等炎性因子在合并高血压2型糖尿病患者早期肾损害的关系及其应用价值。方法测定125例合并高血压2型糖尿病患者和75例健康者(正常对照组)尿β_2-MG、hs CRP、IL-6、血清尿素氮(BUN)、肌酐(SCr)、糖化血红蛋白(Hb Alc)水平,并对检测结果进行统计学处理。结果糖尿病组与正常对照组比较在血清BUN、SCr正常范围时其尿β_2-MG、血清hs CRP、IL-6水平均已升高,差异有统计学意义(P<0.05),且尿β_2-MG与血清hs CRP、IL-6水平呈正相关;Hb Alc水平越高的患者尿β_2-MG、血清hs CRP、IL-6升高越明显。结论不少合并高血压的糖尿病患者BUN、SCr虽然正常,但其肾功能已经下降,尿β_2-MG、血清hs CRP、IL-6与糖尿病早期肾损害有着更良好的相关性,联合检测可明显提高糖尿病肾病诊断符合率,对合并高血压2型糖尿病早期肾损害有更高的临床诊断价值,利于临床早期及时干预。     

糖尿病患者血、尿β2-微球蛋白检测的临床意义

目的:用放射免疫法测定糖尿病患者的血、尿β2-微球蛋白(β2-MG),研究其水平与糖尿病病程、是否伴有高血压、不同的血糖浓度和有无蛋白尿之间的关系,并与血清尿素氮、肌酐相比较,以尽早发现糖尿病肾病。方法:用放射免疫法测定血、尿β2-微球蛋白,糖尿病组与正常对照组进行比较、根据糖尿病病程长短分三组进行比较、糖尿病伴高血压与不伴高血压进行比较、不同血糖浓度之间比较和尿蛋白阳性组与尿蛋白阴性组比较。结果:糖尿病组与正常对照组比较在血清尿素氮、肌酐未升高时,血、尿β2-微球蛋白已升高,并有显著性差异(p<0.01);血、尿β2-微球蛋白随病程的延长而增加,糖尿病伴高血压组与不伴高血压组比较β2-微球蛋白明显增高,血糖浓度越高,β2-微球蛋白升高越明显;蛋白尿阳性组与蛋白尿阴性组比较,β2-微球蛋白升高,有显著性差异(p<0.01)。结论:用放射免疫法测定血、尿β2-微球蛋白可早期发现糖尿病肾病,对于保护肾脏,减少糖尿病的死亡率有重要意义。

应用放射免疫测定法(RIA),对30例感染性疾病病儿作尿β_2-MG、Alb、IgG检测,并与86例正常小儿测试水平对比观察,结果表明感染组尿三项蛋白异常占73.3％,尿β_2-MG、Alb测定值明显高于对照组,2例尿IgG水平增高,提示小儿感染性疾病可导致肾损害,不仅局限于肾小管,严重者可累及肾小球,若能早期控制感染与加强对肾损害的预防保护措施,有利于病情恢复。     

2型糖尿病合并代谢综合征与视网膜病变的相关性

为探讨2型糖尿病合并代谢综合征对视网膜病变的影响,对177例2型糖尿病患者资料进行分析,结果显示:2型糖尿病视网膜病变组的病程、收缩压、空腹血糖、糖化血红蛋白、总胆固醇、甘油三酯、低密度脂蛋白、载脂蛋白B、血尿酸2、4 h尿微量白蛋白、HOMA-IR指数、HOMA-β指数均高于糖尿病非视网膜病变组,差异有统计学意义(P0.05),高密度脂蛋白、空腹胰岛素、空腹C肽低于糖尿病非视网膜病变组(P0.05),差异亦有统计学意义;在2型糖尿病患者中,合并MS组分越多,发生DR的危险性越高;病程、吸烟史、甘油三酯、低密度脂蛋白、空腹血糖、糖化血红蛋白、24 h尿微量白蛋白、收缩压、舒张压、HOMA-IR、HOMA-β是2型糖尿病患者发生视网膜病变的危险因素(P0.05)。由此可知,代谢综合征与糖尿病视网膜病变的发生、发展有着密切关系。

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that     

On the Thermodynamic Limit for Responses to Static Electromagnetic Fields

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the     

An affordable accurate evaluation of the binding conformations predicted by molecular docking studies in bio-system

Franck-Condon factors bridge the gap between theoretical modeling and experimental observations for molecular electronic spectroscopy and electron transfer.Under the displaced harmonic oscillator approximation,multidimensional Franck-Condon factors are decomposed into a product of many one-dimensional(1D)Franck-Condon(FC)factors,and each 1D-FC factor is associated with one Huang-Rhys factor that determines the leading contribution of
